摘要

构建了一个全面评价土地利用规模与结构调整相关的环境影响评价模型体系，包括多样性指数模型、动态度模型、生态系统服务价值评价模型、生态足迹和生态承载力评价模型，并以兰州市为例进行实证研究。结果表明，兰州市生态系统服务总价值增加了3.90×108元，生态赤字减少了14m

/人，其土地利用总体规划基本合理，能在发展经济的同时兼顾生态环境效益。研究结果也显示出该模型体系能够比较客观地评价土地利用规模和结构调整的相关环境影响，有一定的应用推广价值。

Abstract

Abstract:By taking Lanzhou City as study area

the model system that can comprehensively and quantitatively assess the impacts of land use scale and structure adjustment on environment wasestablished including diversity index model

dynamic model

ecosystem service value evaluation model

and eco-footprint and eco-capacity model.Results from the study showed that the ecosystem service value of Lanzhou City increased by 390 million yuan and the ecological deficit dropped 14 m2 per head.The overall landuse planning is basically reasonable and is valuable in developing local economy and preserving its ecological environment.Moreover

the model system can objectively assess the impacts of landuse scale and structure adjustment on environment and thus

it is meaningful to apply and popularize the model.
